This really sucks and I'm sorry for the loss of these two guys. Having lived outside Bozeman in the mountains for six years, I was curious about the telemetry for this location and pulled up this: http://www.wcc.nrcs.usda.gov/nwcc/site?sitenum=384&state=wy data for the Snotel site very close to the site of this accident. It seems difficult to belive there would be any ice left to climb after such warm temps and it serves as a good reminder for all of us to check these sites as part of our trip planning protocol.
